The '90s syndication version stripped out the music, and the DVD/Hulu version took out two music-related gags in Act 1. The music in Act 2 is "Young Blood" by the Coasters and "Heart of Glass" by Blondie; though only a few bars of "Heart of Glass" are played, this episode apparently helped make the song a hit because Johnny announces the title and artist, like a real DJ does. CBS was initially reluctant to allow the characters to mention the names of the songs and groups; you'll notice that in most of the earliest episodes, the DJs never identify the songs they're playing. (Networks back then were reluctant to do anything that smacked of free product placement; it was like giving away advertising time for nothing.) Finally the DJs were allowed to announce or back-announce the songs, and that sometimes helped songs to become more popular.
